JOHANN PAEHIJKE, OF BERLIN, GERMANY.

CONFECTlONERY-BRUSHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 687,542, dated November 2 6, 1901.

Application filed December 13, 1900l Serial No. 39,716. (No model.)

To all whom it may concern.-

Be it known that I, JOHANN PAEHLKE, a citizen of the Empire of Germany, residing in Berlin, Germany, have invented certain new and useful Improvements in Confectionery- Brushing Machines, of which the following is a specification.

This invention relates to brushing machines for removing iiour or the like from confectionery and similar goods. In the manufacture of many kinds of confectionery, as is well known, the same is covered with fine flour, which adheres to the cast pieces and hastobesubsequentlyremoved. In machines of this kind heretofore made this removal was effected by means of a tray containing the goods and reciprocating within a closed chamber, so as to bring the goods in contact with suitable brushes. Such machines have the disadvantage, however, that the driving mechanism for the carriage upon which the tray was placed Was more or less complicated and was located to a considerable extent Within the chamber or chest, and the flour removed from the candy collected upon the mechanism and became soiled by contact therewith, and the mechanism was often clogged and its reliable operation interfered with.

The object of my invention is to construct a machine in which these disadvantages are obviated, and for this purpose the invention consists in the combination,in aconfeot-ionerybrushing machine, of a frame, a chest supported by said frame, a carriage guided in said chest, a tray adapted to be supported on said carriage and provided with a perforated bottom, brushes on opposite sides of the path of movement of said carriage and tray, said brushes having bearings mounted outside of the chest, a slide-rod connected with said carriage and guided at one end through said chest, and a power-transmitting mechanism arranged entirely outside of said chest and communicating reciprocating motion to said carriage through the medium of said slid e-rod, and also communicating rotary motion to said brushes; and the invention consists, further, in certain other combinations of operative parts, which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of myimproved apparatus. Fig. 2 is a vertical transverse section on line 2 2, Fig. 1. Fig. 3 is a vertical longitudinal section,drawn onalarger scale,through the brushes, tray, and carriage; and Fig. 4 is a horizontal section on line l 4, Fig. 1.

`Similar letters of reference indicate corresponding parts.

Referring to the drawings, a, indicates the frame of my improved machine, on which is mounted the main shaft b, which drives the small shaft c by means of pulleys c andf and belt d. On the shaft c is a crank g, which imparts reciprocating motion to a lever t', which is pivoted at one end and connected with said crank by a connecting-rod 71,. The opposite free end of the lever t' is connected by means of a rod 7c with a slide-rod n, a rollerl being mounted on the pivot connecting said rod k and slide-rod n and said roller being guided between suitable guide-rods m. The slide-rod n is guided in the rear end of a chest o, and within said chest is connected in any suitable manner with a carriage p, consisting of an angle-iron frame mounted on rollers p' and adapted to be reciprocated longitudinally in the chest o upon its guiderails a, secured in any suitable manner to the sides of the chest. The sprocket-wheel 11 upon the shaft l) drives by means of a chain s and pulleys t two pairs of brushes t, an upper pair and a lower pair, mounted on the shafts of said pulleys, which shafts eX- tend entirely through said casing, as shown in Fig. 2, and are journaled at their ends at the outside of the casing or chest o in bearing-pieces o, adjustable in a suitable slotted standard f by the adjusting-screws to. The brushes t are so located and arranged that the carriage p with its tray can be moved through between the upper and lower pairs of brushes, the guiderails a' for the carriage being located slightly above the level of the shafts ofthe lower brushes,as shownin Fig. 2.

The confectionery upon the carriage p is vigorously brushed by the brushes, the upper brushes brushing the upper surface of the candies, while the lower brushes find access to the lower surface of the same through the perforated bottom b of the tray, as shown in Fig. 3.

IOO

In order to prevent the flour which is brushed olf the confectionery from accumulatingin the chamber or settling' again the lower portion of the chest opposite said noz'zlez and the lower pair of brushes extends an outlet-pipe A, through which air charged with fiour is drawn from the interior of the chest and delivered into a separating-chamber E, having at its upper part a flour-screen B. The flour cannot pass the screen, but collects in the lower part of the chamber and can be removed from t-ime to time by first removing the door O. From the upper part of the separating-chamber-z'. e., that part protected by the screen B-leads an exhaust-pipe D to an exhaust-fan D', cooperating to produce a strong current of air through the apparatus during the cleaning operation, by which the iour is drawn od as fast as removed from the confectionery. The fan D is preferably operated from a pulley d' on the main shaft b by means of suitable belt-andpulley transmission overthe counter-shaft e.

Having thus described my invention, I claim as ncw and desire to secure by Letters Patent- In a confectionery-brushing machine,

the combination of a frame, a chest supported by said frame, a carriage guided in said chest, a tray adapted to be supported on said carriage and provided with a perforated bottom, brushes within said chest on oppositel brushes, substantially as set forth.y

2. In a confectionery-brushing machine, the/,combination of a frame, a chest supported thereby, a carriage guided in said chest, a tray adapted to be supported on said carriage and providedV 'with a perforated bottom, brushes within said chest on opposite sides of the path of movement of said carriage, said brushes having bearings mounted outside of the casing, a slide-rod connected with said carriage and guided at one end through said chest, a power-transmitting mechanism arranged entirely outside of said chest and communicating reciprocating motion to said carand also communicating rotary motion tov said brushes, a bellows, means for operating the same, a pipe connecting said bellows with the top of said chest adjacent said brushes, and an outlet-pipe leading from said chest, substantially as set forth.

3. In a confectionery-brushing machine, the combination of a frame, a chest supported thereby, a carriage guided in said chest, a tray adapted to be supported on said carriage and provided with a perforated bottom, brushes within said chest on opposite sides of the path of movement of said carriage, said brushes having bearings mounted outside of the casing, a slide-rod connected with said carriage and guided at one end through said chest, a power-transmitting mechanism arranged entirely outside of said chest and communicating reciprocating motion to said carriage through the medium of said slide-rod, and also communicating rotary motion to said brushes, a bellows, a pipe connecting said bellows with the upper `part of said chest adjacent said brushes, a separating-chamber, an outlet pipe connecting said chest and separating-chamber, an exhaust-fan, an exhaustpipe connecting said separating-chamber and exhaust-fan, and means for operating said bellows and exhaust-fan', substantially as set forth.

4. In a confectionerybrushing machine, the combination of a frame, a chest supported thereby, a carriage guided in said chest, a tray adapted to be supported on said carriage and provided with a perforated bottom, brushes arranged in pairs within said chest on opposite sides of the path of movement of said carriage, said brushes having bearings rmounted outside 'of the casing, a slide-rod connected with said carriage and guided at one end through said chest, a power-transmitting mechanism arranged entirely outside of said chest and communicating reciprocating motion to said carriage through the medium of said'slide-rod, and also communicating rotary motion to said brushes, a bellows, means. for operating the same, a pipe connecting said JOHANN PAEHLKE.
